Ground spice was analyzed using IS sieve where it was found that 50% of the total salt passed through sieve number 200 ( mm opening) and retained on sieve number 170 ( mm opening). Calculate the surface area of the salt if 3 kg of the sample having a density of 1040 kgm −3 and a shape factor of is used for grinding.

Advantages of the ball mill . The ball mill offers several advantages and is widely used. These are: It can produce a very fine powder. It is used for batch operation. It can be made continuous operation by including a chamber next to the cylinder. These are separated using a sieve. The ball mill is suitable for both wet and dry grinding processes.

Example The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80 % passed through a 2000 micron sieve. Further size reduction was completed in a x m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the commencement of grinding.
